Precision Twist Drill 5999153 Wire Size 64 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999153 is a jobber-length drill bit sized to wire gauge 64, equivalent to 0.0360 inches in diameter. It is manufactured from high speed steel with a steam oxide coating that reduces friction and provides light corrosion resistance during storage and use. The bit features a 118-degree standard point angle, a regular spiral flute, and a straight-cylindrical shank. Overall length is 1.5 inches with a flute length of 0.625 inches. This is a general-purpose drilling tool intended for use by machinists, tool-and-die workers, and maintenance technicians working on precision or small-diameter hole applications.

This drill bit is suited for drilling small-diameter holes in a range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. Its compact jobber length makes it appropriate for benchtop drill press work, hand drilling with a precision chuck, or CNC and manual lathe operations where a short, rigid setup is required. The web-thinned, tapered web construction improves penetration in harder workpiece materials and reduces thrust force at the cutting edge.

Key Features

• Wire gauge 64 size — 0.0360 inches decimal equivalent for precise small-diameter hole work
• High speed steel construction with steam oxide coating for reduced friction and light corrosion resistance
• 118-degree standard point angle with web-thinned, tapered web for improved penetration
• Regular spiral flute, right-hand cut, 2-flute configuration for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without modification
• Meets ANSI standards; rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.0360-inch straight-cylindrical shank, including benchtop drill presses, CNC machining centers, and hand drills equipped with precision Jacobs-style chucks. Series R10-R15-R18.

Installation Notes

This bit is installed by machinists and maintenance technicians using a standard drill chuck sized to accept small-diameter straight shanks. Secure the shank fully in the chuck and verify concentricity before beginning drilling operations. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, as coolant-through is not supported by this bit. Follow applicable shop safety practices and machine guarding requirements when operating drilling equipment.
